This is useful if you want to monitor traffic. Often, this configuration is used to facilitate data loss prevention (DLP) or network-based intrusion prevention systems. [2] VACL or VACL Ports can be much more discriminating of the traffic they forward compared to a standard SPAN port. They may be set to only forward specific types or specific ...
With a VLAN Management Policy Server (VMPS), an administrator can assign switch ports to VLANs dynamically based on information such as the source MAC address of the device connected to the port or the username used to log onto that device. As a device enters the network, the switch queries a database for the VLAN membership of the port that ...
Likewise XYZ uses IDs 11, 12 and 13 in their network, so X1 and X2 are also trunks with single tagged traffic of IDs 11, 12 and 13. The SP, having one network and one connection between S-Switch #1 and S-Switch #2, must segregate Acme's and XYZ's traffic. Since both Acme and XYZ share some VLAN IDs, traffic cannot be segregated by customer VLAN ID.
pfSense is a firewall/router computer software distribution based on FreeBSD. The open source pfSense Community Edition (CE) and pfSense Plus is installed on a physical computer or a virtual machine to make a dedicated firewall/router for a network. [ 3 ]
This means that all VLANs that are not explicitly configured into another MSTI are members of the CIST. The software supports a single instance of the MSTP Algorithm consisting of the CIST and up to 15 MSTIs. A VLAN can only be mapped to one MSTI or to the CIST. One VLAN mapped to multiple spanning trees is not allowed.
Socket Secure (SOCKS) is a technology created in the early 1990s that uses proxy servers to relay traffic between networks or systems. Application-level gateway (ALG) techniques are a component of a firewall or NAT that provides configureable NAT traversal filters. [2] It is claimed that this technique creates more problems than it solves. [3]

This port can communicate with anything else connected to the primary or any secondary VLAN. In other words, it is a type of a port that is allowed to send and receive frames from any other port on the VLAN. Host Ports: Isolated Port (I-Port): Connects to the regular host that resides on isolated VLAN. This port communicates only with P-Ports.
